This month's MTWC Bulletin has the proposed sporting formula classes for the M3W.
Three classes:
"Standard" with stage 1 mods of free flowing air filter and silencer
"Touring Modified" with stage 2 mods of stage 1 plus ECU Morgan calibrated for stage 2
"Track Modified" with stage 1 mods plus big bore (2,093cc), uprated cams, ported head, big valves and ECU Morgan calibrated for stage 3
So it looks like Morgan (via Aero Racing?) could be offering stage 1, 2 and 3 upgrades shortly.
If so it will be interesting to see the quoted power upgrades and compare with Garage 56
